I have been Comcast/Xfinity customer for almost six years. This March my contract with Comcast ended. I called Comcast to try to reduce my bill. We only need high-speed internet (no TV). I asked if I can get a plan that they currently offer their new customers. The answer was no.
I figured I will call again in a few weeks.
I called again in a few weeks. I asked if I can get a plan they currently offer their new customers. The answer was again no. I have to say, both times the agents were very nice and polite. At the end of the second call I told the agent that if I cancel the plan, you guys (Comcast) will will start calling me in a few weeks asking me to come back? The agent said: yes.
Two weeks after I cancelled and switched to another internet provider Comcast called offering a new plan and asking if I would switch back.
